CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation and claims the prioritybenefit of U.S. patent application Ser. No. 12/506,083 filed Jul. 20,2009, now U.S. Pat. No. 8,370,288, the disclosure of which isincorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to media presentation. Morespecifically, the present invention relates to summarizing a body ofmedia.

2. Description of the Related Art

Bodies of media include text-based, video-based, and audio-based mediaas well as multimedia and video games. In many instances, bodies ofmedia include a story-line. Examples of story-line based bodies of mediainclude text-based media such as an eBook, video-based media such as amovie or television program, and audio-based media such as books ontape. Non-story-based media such as songs, instructional media products,news programs may also comprise a body of media. Additionally, a givenbody of media may include a collection of media. For example, a body ofmedia may include a series of books or movies, or an entire season of atelevision program. Moreover, a particular body of media may alsoinclude a portion of a media unit such as a portion of a book, movie, orsong.

Presently, available summaries for bodies of media are limited topre-composed summaries. An example of such a summary includes recaps ofprevious episodes placed at the beginning of television programs or a‘teaser’ at the end of such a program with respect to a forthcomingepisode. These summaries are contrived by producers or marketeers basedon some general preconception of what would satisfy a typical consumerin order to get them to watch a forthcoming episode or to bring them upto date with respect to prior episodes. Unfortunately, preferences andneeds of most customers are not boilerplate, thus forcing thosecustomers to accept less-than-desirable summaries. As such, there is aneed for providing summaries for bodies of media that are tailored toparticular desires of individual consumers.

DETAILED DESCRIPTION

Embodiments of the present invention allow a single body of media to besummarized in various ways depending on numerous factors such as anindividual consumer's qualities, desires, preferences, and specificmedia playback devices. Examples of such factors include the age of theconsumer, a characteristic of a media playback device displaying oremitting the summary, a level of detail preference of the consumer, anda summary duration preference of the consumer. Summaries can begenerated based on one or more factors that are individually tailoredfor consumers.

FIG. 1 illustrates an environment 100 for providing summaries of bodiesof media. The environment 100 includes a number of networked mediaplayback devices; FIG. 1 includes, for ease of illustration, a consumerelectronic (CE) device 105 such as a Blu-Ray player and a mobile device110, such as a smart phone or portable media playback device. Theenvironment 100 also includes a media server 115 and a third-party webserver 120. A network 125 facilitates communication between the CEdevice 105, the mobile device 110, the media server 115, and thethird-party web server 120. The CE device 105, the mobile device 110,the media server 115, and the third-party web server 120 may eachinclude a summarization engine 130, which facilitates generatingindividualized summaries of bodies of media as discussed in detail withrespect to FIG. 2.

The media server 115 includes any repository for media including bodiesof media and summary information of the same. The third-party web server120 may also function as a repository for media and corresponding mediasummaries. The third-party web server 120 may also allow third partiesto submit their own content via the network 125 to be used as summaryinformation for various bodies of media. Each of the devices 105 and 110and servers 115 and 120 of FIG. 1 include the requisite networkinterfaces, memory, and processing components as may be required tointeract with one another via the network 125.

As noted above, CE device 105 may include any consumer electronicsdevice not specifically designed for portability. Examples of the CEdevice 105 include a home entertainment system such as the PlayStation®3available from Sony Computer Entertainment Inc. or more limited gamehardware platforms of a different albeit inferior manufacture than thoseoffered by Sony Computer Entertainment. Further examples of CE devicesinclude various home theater components such as a Digital Versatile Disc(DVD) player, the aforementioned Blu-Ray Disc player, a Digital VideoRecorder, set-top cable boxes, and personal computers. The CE device 105may include one or more integrated output devices for presenting mediaor be coupled to the same (e.g., a display and speakers).

The CE device 105 can facilitate presentation of locally obtained mediaas may be acquired from a local storage medium or remotely via thenetwork 125. Such media may include bodies of media as referenced abovesummaries of those bodies of media. While CE device 105 may include itsown summarization engine 130, CE device 105 may also access asummarization engine 130 (or information therefrom) over the network125, wherein the engine 130 is actually housed in another device such asthe mobile device 110, the media server 115, or the third-party webserver 120.

The mobile device 110 may include any portable consumer electronicsdevice such as a smart phone, portable media playback device, or gamingdevice. Examples of the mobile device 110 include portable gamingdevices such as a PSP™ and PSP Go from Sony Computer Entertainment Inc.The mobile device 110 may also include car stereos, e-book readers, andportable computers. Similar to CE device 105, the mobile device 110 mayinclude one or more integrated output devices for presenting media ormay also allow for an external coupling to the same. Mobile device 110,like CE device 105, facilitates presentation of bodies of media andsummaries of the same. The mobile device 110, like CE device 105, mayhost its own summarization engine 130 or access a remotely hosted engineover network 125 (e.g., at third-party web server 120).

Media presentation may be shifted between multiple devices. For example,a consumer observing a given body of media presented by CE device 105(e.g., watching a Blu-Ray disc version of “The Dark Knight” on ahome-based Blu-Ray player) may halt presentation of the media midwaythrough the body of media and later resume presentation of the same bodyof media on the mobile device 110 (e.g., a digital download of “The DarkKnight” or a streamed versions provided by the CE device 105). Themobile device 110 may communicate with the CE device 105 via the network125 such that the presentation of the body of media on the mobile device110 resumes at the same point at which the presentation was halted onthe CE device 105. A summarization of the portion of the body of mediapresented by the CE device 105 may be optionally presented to theconsumer on the mobile device 110 upon recommencing playback of themedia on a second device. Additionally, the presentation andsummarization of the body of media on the mobile device 110 may bealtered relative to that by the CE device 105 depending, for instance,on the environment of the consumer, the time span since the body ofmedia was last observed, or a number of other factors, as will bediscussed in greater detail in connection with FIG. 2. Allowing fortransfer and synchronization of media on a number of devices may beimplemented using the likes of the media transport protocol (MTP),iSynch, and SyncML.

FIG. 2 is a block diagram of an exemplary summarization engine 130 thatmay be invoked in environment 100 as referenced in FIG. 1. Asillustrated in FIG. 2, summarization engine 130 includes an interfacemodule 205, a factor determination module 210, a factor analysis module215, a summary module 220, and a media output module 225. The individualprogram components and applications making up the modules of thesummarization engine 130 may be stored in memory of devices such as theCE device 105, the mobile device 110, the media server 115, and thethird-party web server 120. The summarization engine 130 and itsconstituent modules can be executed by a processor to effectuaterespective functionalities attributed thereto. The summarization engine130 may be composed of more or fewer modules or combinations of the sameand still fall within the scope of the present invention. For example,the functionalities of the factor determination module 210 and thefunctionalities of the factor analysis module 215 may be combined into asingle module.

The interface module 205 may be executed to receive an instruction toprovide a summary of at least a portion of a body of media. Theinstruction may be received in response to an action by the consumer ofthe media. Such an action may be detected by an interface or input ofthe CE device 105 or the mobile device 110, which can provide indicia ofthat action to the interface module 205. In one example, the instructioncan be received in response to the consumer accessing a body of media.The interface module 205 may be executable to provide—for selection—asummarization function on an interface of the CE device 105 or themobile device 110.

The factor determination module 210 is executable to determine one ormore factors for providing the summary. Factors may be determinedthrough direct input provided by a media consumer or derived frominformation available to the summarization engine 130 at a particulardevice. Such factors can be wide-ranging and individually suited to thequalities, desires, preferences, and specific devices of a consumer.While specific illustrative examples have been provided, any factor thatpersonalizes or optimizes a summary for a given customer is within thescope of the present invention.

One factor for providing the summary may include a current point ofaccess of the body of media by the consumer. The current point of accessof the body of media can be determined by various measures such asepisode numbers, track numbers, frame numbers, page numbers, andtimestamps. The level of precision or accuracy of the current point ofaccess may vary for different types of bodies of media or be specifiedby the consumer.

A span of time since the body of media was last accessed by the consumermay constitute another factor for providing the summary. The span oftime is the amount of time that has lapsed since the consumer lastaccessed the body of media. The span of time can be measured in any unitof time such as seconds, hours, days, or months. When the constituentdevices of the environment 100 are in communication via the network 125,the span of time may be measured from the time the body of media waslast accessed be it on either the CE device 105 or the mobile device110.

A further factor for providing the summary of the body of media mayinclude a tone preference of the consumer. The tone preference maydescribe a particular tonality, style, or manner of the summary. Toillustrate, an individual consumer may have an ironic sense of humor,and therefore prefer an ironic bend to summaries of bodies of media.Other examples of a tone preference may include comedic, dry, orfactually straightforward.

The environment of the consumer may also be weighted as a factor forproviding the summary. The environment can be descriptive of the actuallocation of the consumer or various environmental considerations. Theactual location may be coordinates determined by a GPS module (notillustrated), cellular triangulation as may be appropriate in the caseof a smart phone or other mobile telephone device with mediafunctionality, or an IP address of the device or network on which aparticular device is operating. Environmental considerations can includeambient light and noise levels, which may be detected by the appropriatelight sensor or microphone in the device.

Qualities of the customer may also be invoked as factors in providingthe summary. For example, the age of the consumer may have an effect onthe summary. Gender may also be factored for providing the summary.These types of factors may be provided to the factor determinationmodule 210 from the consumer via the interface module 205.

Another factor for providing the summary can include one or morecharacteristics of an output device. These characteristics can includeavailable output devices and hardware capabilities. For example,depending on screen size, different summary formats may be preferable. Adevice with a small screen may not be appropriate for textual output assuch output would be too small to be read or would occupy too much ofthe screen area. A device with a larger screen, however, may beappropriate for captions or other text that might accompany the summary.

A level of detail preference of the consumer may also be used as afactor for providing the summary. Some consumers may prefer a verydetailed summary whereas other consumer may only high level details. Afurther factor may include a summary duration preference of theconsumer. More detail for a given portion of the body of media maygenerally result in a longer duration summary, and vice versa.

Still referring to FIG. 2, the factor analysis module 215 is executableto analyze factors identified by execution of the factor determinationmodule 210. Based on one or more of those factors, the factor analysismodule 215 can be further executed to select the summary from aplurality of available summaries stored in memory. The plurality ofavailable summaries may correspond to the same portion of the body ofmedia. Furthermore, the available summaries may be available fromdisparate sources such as the media server 115 and the third-party webserver 120. An example of available summaries is described in connectionwith FIG. 3.

Based on one of the factors being the current point of access of thebody of media, execution of the factor analysis module 215 may result inselection of media that summarized a previous portion of the body ofmedia. Alternatively, execution of the factor analysis module 210 mayresult in selection of a portion after the current point of access toprovide a preview.

When a span of time since the body of media was last accessed by theconsumer is invoked as a factor, the factor analysis module 215 mayselect more detailed summary information for longer spans of time andless detailed summary information for shorter spans of time. Moredetailed summary information may serve to jog the memory of theconsumer. Conversely, less detailed summary information may serve as aquick review.

The location and environmental considerations of the consumer may beused by the factor analysis module 215 to select summary material thatis well suited or pertinent the consumer's surroundings. For example, ina noisy environment as would be reflected by location on a city street,textual information may be selected over audio information to summarizethe body of content. Should location information reflect that a user islocated at home, normal audio presentations may be appropriate. If auser happens to be in a country or other environment where certaincontent may be socially unacceptable, a socially-appropriate summaryvariation may be provided.

The factor analysis module 215 may also use factors such as qualities ofthe customer in selecting summary information. The age of the consumer,for example, can be used in determining whether to censor objectionablematerial. The complexity of the summary may also be determined based onthe age of the consumer.

Characteristics of an output device may be used in selecting summaryinformation by the factor analysis module 215. Some summary formats maybe more desirable based on display size or performance capabilitiesavailable to the digital device 105 of the mobile device 110.

Execution of the summary module 220 facilitates assembly of the summaryinformation selected by the factor analysis module 215 into a cohesivesummary. The summary module 220 may integrate various forms of mediasuch as video, audio, and text. Effects such as cross fade transitionsmay also be added by execution of the summary module 220. The summarymodule 220 also provides the summary to the media output module 225.Through execution of the media output module 225, the summary can bepresented to the consumer by output devices of the digital device 105 orthe mobile device 110.

FIG. 3 is an exemplary content timeline 300 of a body of media. Thecontent timeline includes several transition points such as transitionpoint 305. A transition point may be placed at any point along thecontent timeline 300. Generally, however, transition points are placedat natural transitions in bodies of media. For example, a transitionpoint may be placed between two chapters or two scenes. At eachtransition point there are a number of summaries such as summaries 310.The summaries 310 correspond to the portion of the body of mediaproximal to the transition point 305. The summaries 310 can be mixed andmatched by the summary module 220 to yield a summarization of the bodyof media that is individually tailored for consumers.

The summaries 310 can vary in many ways. The summaries 310 may includevarious levels of detail or duration. The summaries 310 may includetextual, audio, video, or any combination thereof. The summaries 310 maybe flagged as corresponding to certain factors determined by the factordetermination module 210. Metadata may also be used to associate thesummaries 310 with various transition points and factors. In addition,the summaries 310 may include content from the body of media itself. Thesummaries 310 may be generated by the provider or producer of the bodyof media. Alternatively, the summaries 310 may be generated and providedby a third party by way of the third-party server 120. Supplementalinformation associated with the body of media may be included in thesummaries 310. For example, the summaries 310 can be used by individualswho do not need to be caught up, but just do not fully comprehend thebody of media.

FIG. 4 is a flowchart illustrating an exemplary method 400 forsummarizing a body of media. The steps of the method 400 may beperformed in varying orders. Furthermore, steps may be added orsubtracted from the method 400 and still fall within the scope of thepresent invention. The methodology illustrated in FIG. 4 may be embodiedin a computer-readable storage medium and executable by a processingdevice at any one of the devices illustrated in FIG. 1.

In step 405, an instruction is received to provide a summary of at leasta portion of a body of media. The instruction may be received inresponse to an action by the consumer. The instruction may also beprovided more explicitly by the consumer such as though menu choices ofthe digital device 105 or the mobile device 110. The interface module205 may be executed to perform step 405.

In step 410, software stored in memory is executed by a processor todetermine one or more factors for providing the summary. Such factorscan be wide-ranging and individually suited to the consumer's qualities,desires, preferences, specific devices, and so on. Step 410 may beperformed by the factor determination module 210.

In step 415, the summary is selected from a plurality of availablesummaries stored in memory. The plurality of available summariescorrespond to the at least a portion of the body of media. Additionally,the summary is selected based on the one or more factors determined instep 410. Furthermore, the plurality of available summaries may beavailable from disparate sources such as the media server 115 and thethird-party web server 120, or be stored locally on the digital device105 or the mobile device 110. Step 415 may be performed by way ofexecution of the factor analysis module 215.

In step 420, the selected summary is provided to a consumer via anoutput device. Such an output device may be integrated with or coupledto the digital device 105 or the mobile device 110. The selected summarymay be assembled by the summary module 220. The media output module 225may be executed to perform step 420.
